United States copyright registrations, renewals and other catalog entries since 1978 are published online at the U.S. Copyright Office website. Entries prior to 1978 are not published in the Online Catalog. Copyright registrations and renewals after 1890 were formerly published in semi-annual softcover catalogs called The Catalog of Copyright Entries or Copyright Catalog or published in microfiche. The online version called CoCatalog is located at cocatalog.loc.gov and is searchable.
The Copyright Office published the Catalog of Copyright Entries (CCE) in print format from 1891 through 1978. These volumes may often be available at federal depository libraries. From 1979 through 1982, the CCE was issued in microfiche format. The catalog was divided into parts according to the classes of works registered. Each CCE segment covered all registrations made during a particular period of time. Renewal registrations made from 1979 through 1982 are found in section 8 of the catalog. Renewals prior to that time were generally listed at the end of the volume containing the class of work to which they pertained. Effective with registrations made since 1982, the only way to see the CCE is by using the Internet to access the Copyright Office automated catalog. The automated catalog contains entries from 1978 forward. To access the catalog, go to copyright.gov.
The Catalog of Copyright Entries, the Copyright Card Catalog, and the online files are indexes, not reproductions of original documents. To view or copy the original documents yourself, you must visit the Copyright Office. Information such as registration numbers may be obtained from these files. Providing this information yourself rather than paying a fee to have the Office search for it will reduce the cost of obtaining records and copies from the Copyright Office.
